Detailed Description

Fig. 1 shows a schematic structural view of a handle for a garden tool, according to an embodiment of the present invention. As shown in fig. 1, the garden tool may be, for example, a lawnmower, which may generally comprise a main handle 1 and a secondary handle 2. Wherein the secondary handle 2 is rotatably mounted at the primary handle 1. The main handle has a connection portion 11 to which the sub handle is connected. The secondary handle 2 may be formed by two shells 24 spliced to each other. The housing 24 has a rotating portion 21 rotatable around the connecting portion 11. Fig. 2 shows a schematic three-dimensional view of one of the shells 24 of the secondary handle according to one embodiment of the invention. As shown in fig. 2, the rotating portion 21 of the sub-handle 2 has two engagement portions 211. It is understood that the number of the engagement portions 211 may be one. Each engagement portion 211 includes an engagement portion body and a mounting hole 2112, the mounting hole 2112 being located at the center of the engagement portion body. The engagement body may have a circular outer periphery and a plurality of latches 2111 at its inner periphery.

As shown in fig. 1, the handle may further comprise an angle adjustment mechanism 3. Fig. 3 shows a schematic structural view of the angle adjustment mechanism 3 according to one embodiment of the present invention. Fig. 4 shows a partial enlarged view at a in fig. 3. As shown in fig. 3 and 4, the angle adjusting mechanism 3 includes a button assembly. The button assembly may include two button elements 321. Of course, it is understood that in another embodiment, the number of the button elements 321 may be one, as long as the number of the engaging portions is consistent. Fig. 5 shows a schematic structural view of a button element according to an embodiment of the present invention. As shown in fig. 5, each button member 321 has a plurality of teeth 3211 that can engage with the engagement portion 211 of the sub-handle 2. In an initial state, i.e., when the angular adjustment is not performed, the plurality of teeth 3211 are engaged with the plurality of latches 2111 of the engagement portion 211 of the sub-handle 2 such that the rotation portion 21 of the sub-handle 2 cannot rotate with respect to the connection portion 11 of the main handle 1, i.e., the sub-handle 2 cannot rotate with respect to the main handle 1.

As shown in fig. 3 and 4, the angle adjustment mechanism 3 may further include a pulling assembly 31. The pull assembly 31 may include a gripping element 312. The grip element 312 protrudes from the housing 24 of the secondary handle 2, which may include a grip 3121 and an extension 3122. The holding portion 3121 is disposed outside the receiving cavity formed by the two housings 24 of the sub-handle 2 and is located in a hollow area defined by the two housings 24 for facilitating the operator to hold to apply an external force. The extending portion 3122 extends from the lower portion of the holding portion 3121 in a direction away from the holding portion 3121, and one end of the extending portion 3122 is provided in the accommodating chamber of the sub-handle 2. The lift assembly 31 also includes a ramp 311. The ramp 311 may be integrally formed with the gripping member 312 or may be non-integrally connected together to move with the gripping member 312 in a predetermined direction when an external force is applied to the pulling assembly 31 of the gripping member 312. The ramp has two inclined surfaces. It will be appreciated that when the number of engagement portions and button elements is one, the ramp is provided with a bevel.

The number of pushers 33 is consistent with the number of button elements. In the embodiment shown in fig. 3 and 4, the number of pushers is two. Each pusher 33 includes a body 331. The main body 331 has a through hole at a center thereof, and the sub-handle receiving cavity has at least one rotation shaft 22 therein. The body 331 is provided at the rotation shaft 22 through a through hole, and is rotatable about the rotation shaft 22. Each pusher 33 further comprises two abutments 332. The two abutting portions 332 are respectively disposed at two sides of the through hole and extend to the same side along the vertical direction of the body 331 to abut against the ramp 311 and the button member 321, respectively. When the ramp 311 moves in a preset direction together with the grip element 312, the abutting portion 332 of the pusher 33 abutting against the ramp 311 may move along the inclined surface of the ramp 311, so that the pusher 33 rotates about the rotation shaft 22, so that the abutting portion 332 of the pusher 33 abutting against the button element 321 pushes the button element 321 inward to disengage from the engagement portion 211. Wherein the two pushing pieces 33 are provided to bring the two button elements 321 close to each other when pushing the two button elements 321 out of the two engagement portions 211. It will be appreciated that the through hole may be provided at a certain position of the body according to actual needs, not necessarily at a central position, but only by enabling the two abutment portions 332 of one pusher 33 to rotate around the through hole and push the button element 321 to disengage from the engagement portion 211. The pushing member 33 in the embodiment of the present invention has a very simple structure, can be in any shape, has very strong operability, and can be manufactured to be any structure conforming to the casing 24 of the auxiliary handle 2, as long as the rotation is satisfied, and the pushing force of the ramp is converted into the pushing force to the button assembly.

As shown in fig. 3 and 4, in order that the pulling assembly 31 may be automatically reset upon withdrawal of the external force applied to the grip 3121, the pulling assembly 31 may further include a first reset element 313. The first restoring element 313 is configured to be stretched or compressed when the holding element 312 moves in a predetermined direction, so as to drive the pulling assembly 31 to restore when the external force is removed, and further drive the ramp 311 to restore. The first reset element 313 has one end fixed to the first fixing portion 23 in the accommodating cavity of the sub-handle 2 and the other end fixed to the second fixing portion 3111 at the bottom of the ramp 311. In one embodiment, the first restoring element 313 may be, for example, a spring or the like that can deform under an external force and can return to its original shape when the external force is removed. The button assembly may also include a second reset element 322. The second reset element 322 is disposed between the two button elements 321 and is configured to be in a compressed state when the pusher 33 pushes the button elements 321 out of engagement from the two engagement portions 211. The two button members 321 are close to each other when disengaged from the two engagement portions 211. The second restoring element 322 may be, for example, a spring or the like that deforms under an external force and returns to its original state when the external force is removed. Wherein, the end of the pushing member 33 contacting the ramp 311 is configured to be unstressed when the ramp 311 is reset, such that the abutting portion 332 of the pushing member 33 abutting against the button element 321 moves under the reset action of the second reset element 322, and such that the pushing member 33 rotates to reset.

In an initial state, i.e., when it is not necessary to adjust the angle between the main handle 1 and the sub-handle 2, the ramp 311 of the pull-up assembly 31 is in an initial position, in which the button member 321 is engaged with the engagement portion 211, and one abutting portion 332 of the pusher 33 abuts against a portion of the ramp 311 near the end portion 3113, and the other abutting portion 332 abuts against the button member 321. The other pushing member 33 is symmetrically arranged with the pushing member 33 described above. When it is necessary to change the angle between the main handle 1 and the sub-handle 2, it is only necessary to gently apply an external force in the direction indicated by the arrow in fig. 3 to the pulling assembly 31 and rotate the rotating portion 21 around the connecting portion 11. The operation principle is that when the ramp 311 of the pulling assembly 31 moves along a predetermined direction together with the holding member 312, the pushing member 33 simultaneously moves along the inclined surface of the ramp 311 to be pushed by the ramp 311 to rotate, and when rotated, the button member 321 can be pushed to gradually disengage from the engagement portion 211. After the button member 321 is disengaged from the engagement portion 211, an external torsion is applied to the sub-handle 2 so that the rotation portion 21 of the sub-handle 2 rotates with respect to the connection portion 11, and the engagement portion 211 rotates following the sub-handle 2 when the button assembly is disengaged from the engagement portion 211 to adjust the angle between the main handle 1 and the sub-handle 2.

According to the scheme of the invention, the angle between the auxiliary handle 2 and the main handle 1 can be conveniently adjusted due to the angle adjusting mechanism 3. When the angle adjusting device is used, an operator only needs to hold the main handle with one hand and hold the auxiliary handle with the other hand, and lightly pulls the finger of the hand holding the auxiliary handle, so that the angle adjusting device can realize angle adjustment, and is very labor-saving. Since the pushing member 33 converts the pushing force of the ramp 311 to the pushing member 33 into the pushing force to the button assembly, the button assembly can be pushed away from the engagement portion 211 more easily and with less effort when an external force is applied to the grip portion 3121. Therefore, the angle adjusting mechanism 3 has a simpler internal structure, and does not need complicated parts to realize angle adjustment, so that the assembly is simpler.

According to the scheme of the invention, the structure of the pushing piece 33, the inclined table 311 and the button component is skillfully arranged, so that the working principle of the angle adjusting structure is simple, the related parts are simple, the space requirement and the internal arrangement requirement on the accommodating cavity in the auxiliary handle 2 are lower, the product boxing can be effectively improved, the cost of single transportation is reduced, and the connection reliability of the assembly of the auxiliary handle 2 can be met.

In order to prevent the pulling assembly 31 from being pulled excessively, the angle adjusting mechanism 3 may further include a limiting mechanism. The limiting mechanism may include a limiting block 341, a limiting groove 342, and a blocking rib 343. The stopper 341 is disposed at the ramp 311 and protrudes from the surface of the ramp 311. The limiting groove 342 is disposed in the corresponding receiving cavity of the auxiliary handle 2, and is configured to enable the limiting block 341 to move in the limiting groove 342 when the ramp 311 moves along the preset direction. The blocking rib 343 is disposed at the limiting slot 342 and configured to block the limiting block 341 from moving in the limiting slot 342 when the ramp 311 moves to a predetermined position along the predetermined direction. The limiting mechanism is simple in structure, and limiting of the lifting assembly 31 can be achieved only by arranging a limiting block 341 at the inclined table 311 and arranging a limiting groove 342 in the corresponding accommodating space of the auxiliary handle 2 and arranging a blocking rib 343 at the limiting groove 342.

By now it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been shown and described herein in detail, many other variations or modifications of the invention consistent with the principles of the invention may be directly ascertained or inferred from the present disclosure without departing from the spirit and scope of the invention.
